OK, changed my mind. Yes the Noah-ide Covenant was a Jewish thing just as the "dispensation" of the law Jewish because it occurred long before the cross.
Examining Acts 15 it seems that the apostolic council was attempting to revert to it to keep the Judaizers from polluting the gospel of grace through faith.
Acts 15:1 And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.
...
6 And the apostles and elders came together for to consider of this matter.
7 And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
9 And put no difference between us and them, purifying their hearts by faith.
10 Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
11
But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
12 Then all the multitude kept silence...
...
23 And they wrote letters by them after this manner; The apostles and elders and brethren send greeting unto the brethren which are of the Gentiles in Antioch and Syria and Cilicia:
24 Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised, and keep the law: to whom we gave no such commandment:
...
28 For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;
29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
My apologies to all for being so sensitive but a visit to the doctor (both before and after) seems to do that to me nowadays.
